Opening a contract is like walking a tightrope

My thighs are really bruised. I was almost liquidated with a position of 3000u, slowly going down, but I made 1000u. I thought I should just close it, but hesitated for 3 seconds. By some strange chance, it went up a little, and I ended up closing it unexpectedly. The result was a sudden drop, and I missed out on earning an extra 10,000u. For a retail investor like me, 10,000u is truly a dream, just that little bit away! It's so frustrating!
